CVE-2026-19029

HDF5 versions through 2.2.0 are vulnerable to a heap-based buffer over-read within the H5Z__filter_scaleoffset() function located in src/H5Zscaleoffset.c. The root cause occurs when the decoder copies d_nelmts * size bytes from a compressed chunk without verifying if the chunk contains sufficient...

EUVD-2026-93981

A heap-based buffer over-read in H5Zfilterscaleoffset in src/H5Zscaleoffset.c in HDF5 through 2.2.0 lets an attacker cause a denial of service application crash with a crafted HDF5 file. When the stored minimum bits equal the full precision of the datatype, the decoder copies dnelmts size bytes...
